## Technical details

A use-after-free (UAF) vulnerability exists in the WebView component of Google Chrome on Android (CWE-416). The flaw is triggered when the application attempts to access memory that has already been freed, which can be induced by a specially crafted HTML page. A remote attacker can exploit this to execute arbitrary code within the context of the browser's sandbox. The vulnerability was addressed in version 149.0.7827.197. While the NVD description mentions a 'local' attacker, the primary vector for crafted HTML pages in a browser context is typically remote/network-based.
